LCE Software Requirements

All deployments of LCE require the following:

  • An active LCE license
  • RHEL/CentOS 5.x, 6.x, or 7.x, 64-bit
  • Elasticsearch 2.3.3 to 2.4.3
  • Java Runtime Environment, latest version

Additionally, while LCE is active, it requires exclusive access to certain ports. The only services that are required to support remote users are SSH and the LCE interface (lce). If other services are active on the system, conflicts should be avoided on the following default ports:

Port Description
162 SNMP
514 Syslog messages
601 Reliable syslog service messages
1243 Vulnerability detection (if enabled in SecurityCenter)
6514 Encrypted TCP syslog messages
8836 LCE interface
31300 LCE API

Caution: The system running the LCE can operate a syslog daemon, but the syslog daemon must not be listening on the same port(s) that the LCE server is listening on.
